2003 GMC Yukon Brakes Problems

BRAKE FAILURE DUE TO LEAK FROM RUSTED OUT BRAKE LINE UNDER DRIVER SEAT AREA AND LOSS OF BRAKE FLUID.

BRAKES LINES RUSTED WHICH LED TO CATASTROPHIC FAILURE OF BRAKE SYSTEM. REPAIR COST $1,000. THERE ARE MULTIPLE THOUSANDS OF COMPLAINTS REGARDING THIS TYPE OF BRAKE FAILURE IN THIS MAKE, MODEL, & YEAR. THIS SHOULD BE A MANDATORY FACTORY RECALL. SOMEONE IS GOING TO DIE BECAUSE GM IS NOT BEING FORCED TO FIX THEIR FAULTY EQUIPMENT. MY VEHICLE WAS IN MOTION AND WHEN I DEPRESSED THE BRAKE PEDAL THE PEDAL WENT COMPLETELY TO THE FLOORBOARD. I WAS DRIVING STRAIGHT AHEAD IN MODERATE CITY TRAFFIC & NARROWLY MISSED STRIKING THE VEHICLE IN FRONT OF ME ON A CITY STREET. MY MASTER CYLINDER WAS COMPLETELY EMPTY OF BRAKE FLUID WHEN EXAMINED. I WAS TRAVELING 25 MPH AND MY VEHICLE HAS 110,000 MILES. (THE NEXT PAGE WOULDN'T ALLOW ME TO ENTER THE SPEED & MILEAGE INFORMATION WHERE IT WAS REQUESTED)

MY BRAKE LINES ARE RUSTED OUT AS DESCRIBE IN THE ARTICLE BELOW. COSTING ME OVER 650.00 TO REPAIR. LESS THAN 115K ON MY CAR! NEVER HAD TO REPLACE BRAKE LINES BEFORE... I LOST MY BRAKE UN-EXPECTANTLY DURING A RAIN STORM IN COHASSET, MA ON 1/10/2017. LUCKILY I WAS ON A SIDE ROAD COMING TO A STOP SIGN AND NO ACCIDENT OCCURRED NOR WERE MY 3 KIDS IN THE VEHICLE. I SAW THIS ARTICLE BELOW AND DECIDED TO WRITE YOU. HTTPS://WWW.CONSUMERAFFAIRS.COM/NEWS/CONSUMERS-COMPLAIN-OF-CORRODED-BRAKE-LINES-IN-OLDER-GM-TRUCKS-013014.HTML

BRAKE LINES CORRODED RESULTING IN LOSS OF BRAKES AND REAR ENDING SCHOOL BUS. REPLACED ALL BRAKE LINES AT MY COST AS WELL AS THE DAMAGE TO THE FRONT END OF THE TRUCK. NOW, THE KNOWN ABS BRAKE SENSOR ISSUE IS ACTIVATING THE ABS AT LOW SPEEDS.

TL* THE CONTACT OWNS A 2003 GMC YUKON. WHILE DRIVING APPROXIMATELY 40 MPH, THE BRAKES FAILED TO WORK. WHILE ATTEMPTING TO SLOW DOWN, THE BRAKE PEDAL WENT TO THE FLOOR WHEN IT WAS DEPRESSED, BUT FAILED TO STOP THE VEHICLE. THE ABS INDICATOR ILLUMINATED. THE CONTACT SLOWLY DROVE THE VEHICLE TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE HYDRAULIC UNIT NEEDED TO BE REPLACED. THE TECHNICIAN REFERRED THE CONTACT TO A LOCAL DEALER. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VIN WAS NOT PROVIDED. THE FAILURE MILEAGE WAS 142,000.

THE BRAKES FAILED WHILE DRIVING ON A CITY STREET CAUSING MY VEHICLE TO NEARLY STRIKE A NUMBER OF CHILDREN AT A CROSSWALK. AFTER EXAMINATION BY A MECHANIC, IT WAS DETERMINED THAT THE BRAKE LINE HAD CORRODED AND BURST UNDER PRESSURE. I HAVE RECEIVED NO NOTICE OF THIS POTENTIAL FAILURE FROM GMC EVEN THOUGH IT HAS BEEN INVESTIGATED BY THE NHTSA. SHOULDN'T THE MANUFACTURER HAVE AN OBLIGATION TO REPAIR THIS POTENTIALLY LETHAL PROBLEM? AT A MINIMUM I FEEL THAT GMC AND/OR THE NHTSA HAVE A MORAL OBLIGATION TO NOTIFY OWNERS OF AFFECTED VEHICLES THAT THEY ARE DRIVING A POTENTIALLY DEADLY VEHICLE.

WHILE APPROACHING AN INTERSECTION I APPLIED THE BRAKES THE PEDAL WENT TO THE FLOOR ABS LIGHT CAME ON AND THE WAS TOTAL BRAKE FAILURE. GUIDED THE VEHICLE OFF THE ROAD AND HAD IT TOWED TO THE SHOP. THEY FOUND RUSTED BRAKE LINES AT THE ABS VALVE ALONG WITH A RUSTED BACKING PLATE FOR THE VALVE. IN ORDER TO IMPROVE VEHICLE SAFETY THE LINES WILL ALL BE REPLACED WITH STAINLESS STEEL SO THIS DOESN'T HAPPEN AGAIN. THIS IS A VERY POOR DESIGN SINCE A SINGLE FAILURE SHOULD NOT CAUSE TOTAL FAILURE OF A SUPPOSED DUAL BREAKING SYSTEM.

TOTAL BRAKE FAILURE WHILE STATIONARY AND ENGAGING DRIVE MODE IN DRIVEWAY. BRAKE PEDAL WENT TO FLOOR. PARKING BRAKE ALSO SOFT AND INEFFECTIVE BUT RESTORED NORMAL CONDITION SHORTLY THEREAFTER.. NO BRAKE OR ABS SYSTEM SERVICE ALERTS OR FAULT WARNINGS PRIOR TO FAILURE. 'SERVICE BRAKE SYSTEM' ALERT PRESENT AFTER FAILURE. NO OBDS CODES PRESENT. SUSPECT BRAKE LINE CORROSION. APPROXIMATELY 170,000 MILES. RECENT TIRE/BRAKE/ALIGNMENT INSPECTION REVEALED NO ISSUES. THIS IS A VERY CLEAN, "NEW TO ME" USED VEHICLE WITH AN EXCELLENT RECORD OF SERVICE. HAD JUST COMPLETED A TROUBLE FREE 2400 MILE INTERSTATE ROAD TRIP.

I WAS TOWING A 17' BOAT AND CAME TO A STOP SIGN. I PRESSED THE BRAKE PEDAL AND IT WENT TO THE FLOOR. THE YUKON DID NOT SLOW AT ALL. FORTUNATELY, NO ONE WAS COMING AND I ROLLED THROUGH THE STOP SIGN, MADE A RIGHT TURN, AND WENT DOWN A STEEPER HILL. PUMPING THE BRAKES AS I WENT HAD NO EFFECT. THE DASH SHOWED A 'SERVICE BRAKE' MESSAGE. I APPLIED THE PARKING BRAKE AND DOWN-SHIFTED, WHICH SLOWED IT ENOUGH THAT I WAS ABLE TO SWING WIDE INTO THE OPPOSING TRAFFIC LANE AND BARELY MAKE THE TURN AT THE BOTTOM OF THE HILL. I PULLED OFF TO THE SIDE OF THE ROAD WITH THE RIGHT-WHEELS ON A SOFT SHOULDER BEFORE THE VEHICLE SLOWLY CAME TO A STOP. I REFILLED THE BRAKE RESERVOIR AND HAD MY WIFE PRESS THE BRAKE PEDAL. IT WENT TO THE FLOOR AS BRAKE FLUID SHOT ONTO THE HOT EXHAUST MANIFOLD, LEAKING FROM A RUSTED JOINT WHERE THE STEEL BRAKE LINE JOINED A FLEXIBLE, BRAIDED LINE UNDER THE HOOD. THE BRAKE LINES WERE HORRIBLY RUSTED, UNLIKE ANYTHING I HAD EVER SEEN IN MY 35+ YEARS OF DRIVING AND OWNING VEHICLES (INCLUDING 20 CARS AND LIGHT TRUCKS). THIS YUKON HAS SPENT ITS ENTIRE LIFE REGISTERED IN VIRGINIA AND HAS LESS THAN 80K MILES ON IT. I CAN'T IMAGINE WHAT THEY ARE LIKE IN NORTHERN STATES. LOOKING ONLINE, I DISCOVERED THAT THIS WAS A KNOWN PROBLEM THAT THE NHTSA HAD INVESTIGATED. WHY WAS I NOT WARNED? I COULD HAVE BEEN INJURED OR KILLED, AS COULD HAVE ANOTHER MOTORIST OR PEDESTRIAN! WHEN I CALLED MY LOCAL GMC DEALER (OURISMAN OF ALEXANDRIA, VA), THE SERVICE ADVISOR CLAIMED TO BE UNAWARE OF THE PROBLEM, THE GM SERVICE BULLETINS THAT HAD BEEN ISSUED ON IT, AND THE AVAILABILITY OF THE PRE-BENT LINES AS A DISCOUNTED KIT FROM GM. HE ESTIMATED A FOUR-FIGURE LABOR BILL TO DO THE WORK, SO I AM DOING AS MUCH OF IT AS I CAN MYSELF USING NICKEL-COPPER BRAKE LINE AND A FLARING TOOL. PEOPLE ARE GOING TO DIE FROM THIS IF THE NHTSA DOES NOT FORCE GM TO DO A RECALL.

BRAKES FAILED WHILE DRIVING ON CITY STREET WITH NO WARNING COULD NOT STOP AT RED LIGHT. IMMEDIATELY PULLED OVER AND NOTICED BRAKE FLUID LEAKING FROM LEFT SIDE OF VEHICLE FROM A BROKEN BRAKE LINE.

TL* THE CONTACT OWNS A 2003 GMC YUKON. WITHOUT WARNING, THE BRAKE PEDAL TRAVELED TO THE FLOORBOARD AND BRAKE FLUID WAS LEAKING. A MECHANIC REPLACED THE REAR BRAKE LINES; HOWEVER, 1,000 MILES LATER, THE FRONT BRAKE LINES ALSO FRACTURED. THE MECHANIC REPLACED THE FRONT BRAKE LINES AND INDICATED THAT THERE WAS EXTENSIVE RUST AND CORROSION. ALL OF THE BRAKE LINES NEEDED TO BE REPLACED OR THE FAILURE COULD RECUR. THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 04V045000 (SERVICE BRAKES, HYDRAULIC). THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 100,000.

BRAKE LINE FAILURE - ST. LOUIS MO. BRAKES FAILED WHILE ATTEMPTING TO SLOW FROM 60MPH SPEED ON CHRISTMAS DAY. NARROWLY ESCAPED ACCIDENT/COLLISION. 2 BRAKE LINES WERE FOUND RUPTURED/SPLIT DUE FROM RUST/CORROSION THEN REPAIRED. OTHER BRAKE LINES ARE SHOWING CORROSION & WILL NEED ATTENTION SOON. VEHICLE IS 2003 GMC YUKON WITH 101,300 MILES.

LOST ALL BRAKING , TOOK TRUCK TO REPAIR SHOP AND THE BRAKE LINES HAD CORRODED AND HAD SEVERAL HOLES IN THEM. I HAD TO REPLACE ALL THE METAL LINES ON THE VEHICLE. BRAKES WERE FINE HOOKED UP UTILITY TRAILER AND PULLED OUT OF MY DRIVEWAY. GOING DOWN HILL, APPLIED BRAKES AND THE PEDAL WENT ALL THE WAY TO THE FLOOR.

TL* THE CONTACT OWNS A 2003 GMC YUKON. WHILE DRIVING APPROXIMATELY 55 MPH, THE CONTACT DEPRESSED THE BRAKE PEDAL AND IT TRAVELED ALL THE WAY DOWN TO THE FLOORBOARD. THE CONTACT HAD TO GEAR DOWN IN ORDER TO STOP THE VEHICLE. THE VEHICLE WAS TOWED TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE BRAKE FLUID LINE NEEDED REPLACEMENT. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS UNKNOWN. THE APPROXIMATE FAILURE MILEAGE WAS 113,000.

I LET MY FREIND TAKE VEHICLE AND SHE SAID WHEN SHE BRAKED THE PEDAL WENT TO FLOOR.SHE WAS HALF MILE AWAY AND MADE IT BACK .I LOOKED AT LEVEL IN MASTER CYLINDER AND HAD TO PUT FLUID IN.NOTICED BRAKE FLUID ON THE UNDERCARRIGE WHICH LED ME TO RUSTED BRAKE LINE UP FRONT.

I LOST ALL BRAKING ABILITY WHILE TRAVELING THE INTERSTATE HIGHWAY. I WAS ABLE TO STOP THE VEHICLE AND FOUND BRAKE FLUID FLOWING FROM THE MAIN BRAKE LINE FEEDING THE ANTI-LOCK CONTROLLER.

I WAS DRIVING WITH MY 14MONTH OLD BABY IN THE CAR AND ALL OF A SUDDEN I HAD NO BRAKES AT ALL. MY PARKING BRAKE COULDN'T STOP ME EITHER SO I PUT THE CAR IN NEUTRAL AND THEN FORCED IT INTO PARK SO I DIDN'T CRASH. THE BRAKE LINES ARE COMPLETELY CORRODED AND I DIDN'T HAVE ANY NOTICE OR IDEA UNTIL THE BRAKES WERE ALREADY GONE.

IWAS DRIVING AT LOW SPEED WENT TO STOP AT STOP SIGN WHEN BRAKE PEDDLE WENT TO FLOOR.I CRASHED INTO STOP SIGN TO STOP . TRUCK WAS TOWED TO DEALER. I WAS TOLD TO MAJOR BRAKE LINE BURST. TRUCK IS NOW AT DEALER BEING FIXED. AT A PRICE OF 2800.00. SOMETHING HAS TO BE DONE. THIS CAN'T GO ON ANY LONGER.

REAR BRAKE LINE BURST WITHOUT WARNING AND BRAKE PEDAL WENT TO THE FLOOR. UPON INSPECTION THE BRAKE LINE IS COMPLETELY RUSTED OUT. *TR

THERE IS A RECALL #05068 THAT DESCRIBES EXACTLY WHAT HAPPENS WHILE DRIVING MY CAR. IT OCCURS EVERY TIME I DRIVE MY CAR, EVERY TIME I ACCELERATE AND BRAKE. (2003 GMC YUKON XL). HOWEVER, GMC CLAIMS MY CAR "ISN'T EFFECTED" AND THEY REFUSE TO FIX IT. MY ISSUES ARE 1. GETTING DANGEROUS, AS THE CAR BOGS AND WON'T ACCELERATE WITHOUT A PERIOD OF HESITATION AND THEN IT GIVES TOO MUCH ACCELERATION WHICH CAN BE BAD IF I'M ON A SLIPPERY SURFACE. ALSO, THERE IS A COMMON PROBLEM ON THESE VEHICLES WHICH IS ANOTHER PROBLEM I AM EXPERIENCING: 2. MY ABS KICKS IN RANDOMLY, EVEN IF THE PAVEMENT IS TOTALLY DRY AND CLEAR. APPARENTLY, THIS IS CAUSED BY A CORRODED MOUNTING SURFACE FOR THE FRONT WHEEL SPEED SENSORS. THE CORROSION BUILDS UP CAUSING EXCESSIVE GAP BETWEEN MOUNTING SURFACE AND WHEEL SPEED SENSOR WHICH CAUSES A LOSS OF WHEEL SPEED SENSOR SIGNAL. WHEN THE ABS MODULE SEES THE LOSS OF SIGNAL IT THINKS THE VEHICLE IS SLIDING OUT OF CONTROL SO IT WILL ACTIVATE THE TRACTION CONTROL OR ABS. DESCRIPTION FROM RECALL #05068: CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES MAY EXPERIENCE UNWANTED ANTILOCK BRAKE SYSTEM (ABS) ACTIVATION. THIS CONDITION IS MORE LIKELY TO OCCUR IN ENVIRONMENTALLY CORROSIVE AREAS. THIS RECALL WILL BE LAUNCHED IN THE "SALT BELT" STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MARYLAND, MASSACHUSETTS, MAINE, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT... HAZARD:THIS CAN CAUSE INCREASED STOPPING DISTANCES DURING LOW-SPEED BRAKE APPLICATIONS, WHICH COULD RESULT IN A CRASH.
